Rubik's Trimid
The Rubik's Triamid is a puzzle similar to the Rubik's Cube but is pyramid shaped with hexagonal pieces. The puzzle was invented by the same person who invented the Rubik's Cube Erno Rubik.
Pieces
Each piece of the puzzle has four faces. Of the ten pieces:
- six pieces have two colours, and
- four pieces have three colours (that is, they have only one colour repeated).
In the solved state, the four pieces with three colours must lie on the end points of the pyramid.
